Effects of the different types of DNA mutations on protein sequence Point mutations in the coding region of DNA can have one of three consequences: 1) No effect if the mutated codon still codes for the same amino acid. 2) It can result in the protein having one different amino acid. The effect on protein function can vary from no effect to devastating diseases such as cycstic fibrosis.

- To connect the idea of mutations back to our discussion of DNA and proteins, here are some examples of how a mutation in the DNA can lead to a change in the protein: 1) A number of nucleotides not divisible by three is either inserted into or deleted from the DNA.utation. As discussed in the introduction, mutations are changes in the genetic code that lead to different traits arising. These mutations can be passed down genetically and either be lost or become fixed.

How Gene Mutation Works Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.

How Gene Mutation Works 1 Silent Mutation: Although a change in the DNA sequence occurs, this type of mutation does not change the protein that is to be produced. 2  This is because multiple genetic codons can encode for the same amino acid. 3  Amino acids are coded for by three nucleotide sets called codons.

Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations But the truth is that most mutations are not that extreme. In biology, a mutation is any change in the nucleotide sequence of DNA. Some mutations affect large sections of DNA, and others only affect certain points along the DNA strand. These small, specific mutations are called point mutations.ut the truth is that most mutations are not that extreme. In biology, a mutation is any change in the nucleotide sequence of DNA.

How Can a Mutation in DNA Affect Protein Synthesis? Point Mutations. A point mutation is a single-letter swap -- an exchange of two bases (adenine to cytosine, for example) at a single location in the DNA molecule. Since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein. Sometimes a change in the protein's amino acid sequence can have dramatic results. For example, sickle cell disease occurs when a single-point mutation in the gene that encodes the hemoglobin molecule results in deformed red blood cells.

Mutations A mutation is a change in the base sequence of DNA that can affect the structure and function of proteins when they occur within a gene. Mutations can be spontaneously caused by copying errors during DNA replication or induced by exposure to external elements such as chemical mutagens, radiation or viruses.oint Mutations. Point mutations are changes to one base in the DNA code and may involve either: 1  The substitution of a base (e.g. 2  ATG becomes ACG). 3  The insertion of a base (e.g. 4  ATG becomes ATCG). 5  The deletion of a base (e.g. 6  ATG becomes AG).

- If an amino acid is altered in the active site region of a protein, it may decrease or destroy the ability of the protein to perform its function. This kind of mutation often leads to a classic recessive allele--an allele which does not produce a functional gene product.

How Gene Mutation Works This change can affect a single nucleotide pair or larger gene segments of a chromosome. DNA consists of a polymer of nucleotides joined together. During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.

What is a gene mutation and how do mutations occur? A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.or example, some mutations alter a gene’s DNA sequence but do not change the function of the protein made by the gene. Often, gene mutations that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed and an altered protein is produced.

2 Describe how point mutation and frameshift mutation affect the synthesis of proteins? A point mutation is a change in a single base pair in DNA. A change in a single nitrogenous base can change the entire structure of a protein because a change in a single amin…o acid can affect the shape of the protein. A frameshift mutation is a mutation in which a single base is added or deleted from DNA. A single base is lost from a DNA strand which causes this new sequence with the deleted base, to be transcribed into mRNA. Then, the mRNA is out of position by one base. As a result, every codonafter the deleted base is different.

- Mutation can result in several different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.utations in the structure of genes can be classified as: , 1  such as those affecting a small gene in one or a few nucleotides, including: 2  Point mutations, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another. 3  These changes are classified as transitions or transversions.

- How Mutations Affect Protein Synthesis. In order to understand how mutations affect protein synthesis, it is important to understand the process by which proteins are made (synthesized) and what a mutation is. Both of these occur on the cellular level of all living beings.Steps of Protein Synthesis. There are three major protein synthesis steps:ikewise, the protein made from the “recipe” of a mutated gene will not be the correct protein. Many small gene mutations do not cause major problems. But other mutations can have very serious health consequences because of how they affect protein synthesis. An example of a mutation is the sickle cell gene.

Mutation Since genes are composed of DNA, nearly anything that can change the structural composition, sequence, physical integrity, or length of a DNA molecule can cause mutations. Breakages may be caused by physical damage such as being severed by ice crystals in a frozen cell or violent agitation from high temperature.

Frameshift Mutation Definition with Example Sometimes substitutions may not effects the protein structure, such mutations are called silent mutations and sometimes they may change an amino-acid-coding codon to a single stop codon and cause an incomplete protein. This can seriously affect the protein structure which may completely change the organism.
